Maxim Integrated MAX16040

The MAX16033–MAX16040 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in microprocessor (µP) systems. The devices significantly improve system reliability and accuracy compared to other ICs or discrete components. The MAX16033–MAX16040 provide µP reset, backup-batwww.DataSheet4U.com tery switchover, power-fail warning, watchdog, and chip-enable gating features.

GENERAL DESCRIPTION

The MAX16033–MAX16040 operate from supply voltages up to 5.5V. The factory-set reset threshold voltage ranges from 2.32V to 4.63V. The devices feature a manual-reset input (MAX16033/MAX16037), a watchdog timer input (MAX16034/MAX16038), a battery-on output (MAX16035/MAX16039), an auxiliary adjustable reset input (MAX16036/MAX16040), and chip-enable gating (MAX16033–MAX16036). Each device includes a power-fail comparator and offers an active-low pushpull reset or an active-low open-drain reset. The MAX16033–MAX16040 are available in 2mm x 2mm, 8-pin or 10-pin µDFN packages and are fully specified from -40°C to +85°C.
